The birds, the bees, and the deep freeze: is there international consensus in the debate over assisted reproductive
Abstract:
This Comment traces assisted reproductive technologies from their historical beginnings in early artificial insemination techniques, through the revolutionary advent of in vitro fertilization two decades ago, and continues to current experimental procedures such as embryo twinning and cryopreservation of ova. It then examines the worldwide controversy surrounding clinical use of these technologies and international attempts to resolve these issues. The final focus is on whether or not a consensus exists within the international legal community on how to tackle the complex issues presented by recent advances in reproductive technology.
